AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
632 PM EST MON DEC 3 2007
.SYNOPSIS...
AN UPPER AIR DISTURBANCE WILL BRUSH MUCH OF WEST VIRGINIA AND
PARTS OF NORTHERN VIRGINIA TONIGHT. WEAK HIGH PRESSURE WILL
PRECLUDE A CLIPPER TYPE LOW BISECTING VIRGINIA BY WEDNESDAY
AFTERNOON. HIGH PRESSURE AT THE SURFACE AND ALOFT WILL REBUILD AND
ANCHOR OFF OF THE SOUTHEASTERN COAST BY THIS WEEKEND.
&&
.NEAR TERM /THROUGH TUESDAY/...
STRONG PRESSURE GRADIENT BETWEEN HIGH PRESSURE OVER THE MISS VALLEY
AND LOW PRESSURE DEEPENING OFF THE NEW ENG COAST WILL KEEP WINDY
CONDITIONS ACROSS THE CWA INTO TONIGHT. FOR THE MOST PART...WINDS
HAVE NOT BEEN AS STRONG AS FORECAST...WITH ONLY A FEW GUSTS OVER 50
MPH IN THE HIGH ELEVATIONS. HOWEVER...BOT NAM AND GFS CONTINUE TO
SHOW AN INCREASED LOW LEVEL JET THIS EVENING AS THE TAIL END VORT IN
THE UPPER TROUGH PASSES BY TO OUR NORTH. I HAVE SEEN TOO MANY TIMES
WHEN THE WINDS PICK UP AFTER SUNSET IN THE HIGH ELEVATIONS ALONG THE
BLUE RIDGE TO DROP THE HIGH WIND WARNING AT THIS POINT. STILL THINK
THERE IS A GOOD CHANCE TO SEE SOME WIND GUSTS NEAR 60 MPH-
ESPECIALLY IN THE NRN MTNS OF NC...THE BLUE RIDGE IN FAR SW VA...AND
THE HIGHLANDS UP TOWARD BATH COUNTY. THERE ARE ONLY A FEW PEAKS
ELSEWHERE IN THE HIGH WIND WARNINGS THAT HAVE A GOOD CHANCE TO SEE
GUSTS TO 60 MPH...BUT SINCE A WARNING IS UP WE HAVE LEFT IT GOING. I
ALSO HAVE KEPT A BUFFER WIND ADVISORY IN THE FOOTHILLS OF THE BLUE
RIDGE IN CASE THE INVERSION LOWERS ENOUGH LATER THIS EVENING FOR
SOME STRONGER WIND GUSTS EAST OF THE CREST. AS FOR LOW TEMPS
TONIGHT...WE SHOULD HAVE GOOD MIXING ALL AREAS...SO I STAYED CLOSE
TO THE MOS GUIDANCE WHICH SHOULD HAVE A GOOD HANDLE ON TEMPS.
TRAJECTORY FOR GREAT LAKE MOISTURE TO PRODUCE UPSLOPE SNOW SHOWERS
LOOKS TO BE FURTHER NORTH THAN THE CWA...PERHAPS WESTERN GREENBRIER
WILL BE ON THE SOUTHERN EDGE. I LEFT LIKELY POPS IN WESTERN
GREENBRIER...AND HAVE AN INCH OR TWO ACCUMULATION THERE. LITTLE OR
NO ACCUMULATION FOR REST OF WESTERN SLOPES IN SE WV AND INTO BATH
COUNTY...WITH CHANCE POPS.
TUESDAY...THE FLOW BACKS MORE TO THE WEST OR SOUTHWEST BY AFTERNOON
IN ADVANCE OF AN APPROACHING CLIPPER. MODELS HAVE MID AND HIGH
CLOUDS SPREADING IN BY AFTERNOON AS WELL. THIS MAY HOLD TEMPS DOWN
IN THE MTNS- WOULD BE A CHILLY DAY IN ANY EVENT AS 850 MB TEMPS ONLY
RECOVER TO -4 TO -7C. ONCE AGAIN...I STAYED CLOSE TO MOS GUIDANCE FOR
MAX TEMPS TUESDAY.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
AREA OF LOW PRESSURE CUTTING THROUGH THE LOWER OHIO VALLEY WILL BE
THE FOCUS OF THE SHRT TERM. THE NAM AND SREF MEMBERS ARE NOW
SHIFTING SOUTH TOWARDS THE GFS/ECMWF/UKMET. THUS...ITS MORE LIKELY
FOR SOME ACCUMULATING SNOW ACROSS OUR NW COUNTIES...MAINLY IN WEST
VA. DYNAMICS ARE NOT TOO SHAPPY FOR A CLIPPER TYPE LOW THIS TIME OF
YEAR...WITH A 120KT H5 JET. A POTENTIAL VORTICITY MAX...ADVECTION OF
LOWER TROPOSPHERIC HEIGHTS...AND WEAK FRONTOGENESIS AT A SATURATED
LEVEL ON CROSS SECTIONS...ALL LINING UP AROUND 12Z WEDNESDAY. IF H85
TEMPS WERE CLOSER TO -10C...BETTER CRYSTAL GROWTH WOULD OCCUR...BUT
WITH AIR ONLY AROUND -5C AT H85...MOST OF THE QPF WILL BE WASTED IN
THE MELTING LAYER. NONETHELESS...THE HIGHEST ELEVATIONS OF WESTERN
GREENBRIER STAND TO SEE A COUPLE INCHES OF SNOW LATE TUESDAY NIGHT
THROUGH WEDNESDAY NIGHT. FARTHER SOUTH...FORECASTING CHALLENGE WILL
BE HOW FAST TEMPS CAN DROP BEFORE MID DECK OF CLOUDS ARRIVES TUESDAY
NIGHT. MIN TEMPS WILL PROBABLY BE REACHED NEAR MIDNIGHT...WITH SLIGHT
RECOVERY ONCE CLOUDS ARRIVE...EXCEPT IN THE EAST WHICH WILL BE ABLE
TO DECOUPLE. SOME OF THE SHELTERED VALLEYS IN THE BLUE RIDGE WILL
LIKELY FALL BELOW FREEZING. ALTHOUGH A DRY LAYER WILL BE IN PLACE
WITH MOSTLY VIRGA...THERE MAY JUST BE ENOUGH QPF REACHING THE
GROUND...SO THAT A CHC OF FREEZING DRIZZLE WAS INSERTED AFTER 6Z
WEDNESDAY. ENOUGH WARM AIR WILL FILL AHEAD OF THE SYSTEM EARLY
WEDNESDAY...WITH A RAIN/SNOW MIX DURING THE DAY...STAYING ALL SNOW
IN THE HIGHEST SPOTS WEST OF THE BLUE RIDGE. NEAR FREEZING TEMPS AND
A STILL RATHER WARM GROUND WILL LIMIT ACCUMS THERE TO AN INCH AT
MOST. A REINFORCING SHOT OF COLD AIR...THIS TIME CLOSER TO -10C AT
H85....SHOULD MEAN AN EVENING OF SNOW SHOWERS AGAIN FOR MUCH OF SE
WVA WITH LIGHT ACCUMS...WITH SOME FLURRIES SURVIVING INTO THE BLUE RIDGE.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
BOTH THE ECMWF/GFS ARE PUMPING HEIGHTS UP QUICKER THAN YESTERDAYS
RUNS...AND THIS WEEKS BOUT WITH WINTER MAY BE A DISTANT MEMORY BY
THIS TIME NEXT WEEK. WITH WHAT LOOKS TO BE THE RETURN OF THE
SOUTHEAST RIDGE...MOST PRECIP CHANCES MAY GET DEFLECTED TO OUR
NORTHWEST. IT WILL TAKE A TROUGH DEVELOPING IN THE SOUTHWEST...TO
PUSH DOWN THE SE RIDGE BY THE MIDDLE OF NEXT WEEK. BEFORE THEN...A
STRING OF ABOVE NORMAL DAYS TEMP WISE LOOKS GOOD...ESPECIALLY
SUNDAY...MONDAY AND TUESDAY.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
BEST PRESSURE RISES ARE ALONG THE VA/NC COAST THIS EVENING...HOWEVER
50-55 KT LEE SIDE JET WILL KEEP WINDY/GUSTY CONDITIONS IN THE AREA
THROUGH 06Z TUESDAY. INVERSION LOWERS SOME OVERNIGHT BUT THINK THE
STRONGEST WINDS WILL BE ABOVE 3KFT. DURING THE DAY TUESDAY...WINDS
WILL RELAX SOME BUT STILL REMAIN BREEZY (10-18KTS) WITH A FEW
STRONGER GUSTS ACROSS THE MOUNTAINS.
MVFR CLOUDS LIKELY ON WESTERN SLOPES THROUGH TONIGHT WITH A FEW
LIGHT VFR SNOW SHOWERS POSSIBLE. VFR CONDITIONS TO RETURN TO THE
ENTIRE AREA BY MID MORNING TUESDAY.
AN UPPER LEVEL DISTURBANCE WILL TRACK ACROSS THE OHIO VALLEY
TUESDAY NIGHT AND INTO THE CENTRAL APPALACHIANS WEDNESDAY. THIS
WILL BRING THE NEXT CHANCE FOR RAIN/SNOW SHOWERS AND WIDESPREAD
MVFR CEILINGS...ESPECIALLY IF THE SHORT WAVE TRACKS TO THE SOUTH
OF THE FORECAST AREA. UPSLOPE SNOW SHOWERS WILL PERSIST IN THE
WEST VIRGINIA MTNS THROUGH THURSDAY MORNING...OTHERWISE VFR
CONDITIONS ARE EXPECTED AFTER THE DISTURBANCE CLEARS THE AREA.
